    Recently my laptop stopped recognising my iomega 1TB ex hd. I can see it in device manager, but not in Computer. Any attempts at data retrieval have been unsucessful - either the data retrieval program cannot 'see' the ex hd, or it takes a ridiculously long time to scan (even a small part of) it. I think the issue may be related to it not having been formatted before use, though I was able to save to it (and subsequently access those files until recently). I do not believe that it is a mechanical problem (there is no clicking noise), though (further to researching my problem on the 'net - to this point with no solution) I do not have the expertise to know what to do next. I suspect that there MAY be a straightforward solution to my problem, and I am trying to avoid sending the hd to a expensive specialist data retieval lab if I can avoid it. I can post any further information that might be required; I'm just not sure what kind of info might be relevant. I would GREATLY appreciate any help you or your members might give me. Thanks.

    i assume that the external hdd is usb correct? if so just try other usb ports. try it on another computer to isolate the problem (if it works on another computer, it is not hdd failure, its a problem with original pc).

    if it is esata drive (im not sure) but you have to plug in external power?

    or if you use ide to usb, you have to experiment with jumpers( put it on master, if not working, csel, and if that doesnt work, slave).

    sorry i might not be much of help but i dont know about external hard drives.

    Thanks for the quick reply. I have tried all usb ports on the laptop (as well as another laptop). None solve this problem. Yes, I have to plug the ex hd into a power source, but there doesn't seem to be a problem here since the ex hd power light activates when plugged in (and attached to the laptop). I don't have the knowledge to understand your suggestions about jumpers and slaves, though if this involves opening the ex hd case, I wouldn't be confident doing this myself. If anyone else has a suggestion, I would be most appreciative. Thanks.

    Thanks for your thoughts. Aside from voiding my ex hd warranty when I open the case, is there any increased danger of losing my data if I try this?

    There's no extra risk if you take your time. Don't force anything and don't drop the drive.
    Place the drive on a clean surface away from any source of accidental damage.

    Does this suggestion indicate that you believe that the issue may be in the connection(s) between the case and my PC?

    Also, if this doesn't work, would I still be able to send it to a 'clean' lab for data retrieval, or would opening the case already have exposed its insides to stuff that the clean lab is clean of, if you know what I mean?
    Thanks again.

    When you open the case you'll see an ordinary hard drive. You won't be exposing any critical components.

    Okay, if I've nothing to lose, I'll get one of those cables and give it a try. If anyone else has any ideas in the meantime, please don't hesitate to post. Thanks again.

    Pay attention to whether the drives spins up when the power is connected and don't hesitate to try the recovery software if needed.
    Good luck.
